APPARATUS FOR FUMIGATING.

Serial No. 646,749.

To all whom it may concern Be it known that we, J AMES W. SooTT andCHARLES A. SCOTT, citizens of the United States, residing at Kokomo, inthe county of Howard and State of Indiana, have invented a new anduseful Apparatus for Fumigating, of which the following is aspecification.

This invention has reference to improvements in apparatus forfumigating, and its object is to provide a simple and eflicientfumigating apparatus which may be readily transported without danger offumes of a disinfectant escaping from the apparatus when not in use.

In accordance with the present invention there is provided a devicecomprising a heating chamber containing a substance capable of beinglighted and thereby constituting a source of heat, another chamberarranged to be in part seated or nested in the first named chamber andcontaining a mass of suitable fumigating material, the second chamberhaving perforations or passages through its walls for the escape of thedisinfectant in a gaseous form due to the action of the heating chamber,and a third chamber adapted toin part enter or nest in the furn1- gatingchamber, the third chamber being designed to receive water and freelyopen at one end, so that the water in the form of vapor or steam mayreadily escape to the atmosphere. The water carrying chamber is soarranged that it may be inverted and then be applied to the disinfectantholding chamber in a manner to close all openings therein, so that thedisinfectant may not escape when the parts are assembled fortransportation.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawings forming a part of this specification, with theunderstanding, however, that while in the drawings there is shown apractical form of the invention, it is not confined to any exactconformity with the particular arrangement shown and described, but maybe variously modified so long as the salient features of the inventionare retained.

In the drawings :-Figure 1 is a central section through the device withthe parts in position for use. Fig. 2 is a like section with the partsassembled for transportation.

Referring to the drawings, there is shown a heating member 1 comprisinga preferably cyhndrical structure closed at one end and open at theother and of practically the same diameter throughout, the walls of thischamber or compartment having openings 2 therethrough between the twoends of the member. At the closed end of the member or chamber 1 andinterior thereto there is provided a mass 3 of some suitable material,such as parafiin or other substance capable when heated of feeding awick 4 which may be lighted, and thereby produce a flame of sufficientintensity to supply the necessary heat for the purposes of the presentinvention. For convenience of description, the mass 3 with its wicktwill be termed a candle, but it will be understood that this term maybe taken as indicative of any heating means for the purpose.

Adapted to the open end of the chamber or member 1 is another member 5of similar contour, having a closed end 6 reduced in diameter so as tofit in the open end of the member 1, with ledges 7 adapted to rest onthe walls of the member 1, at its open end, while the main portion ofthe walls of the member 5 are flush with the walls of the member 1.. Themember 5, like the member 1, may be cylindrical and is provided near itsopen end with a circular series of perforations or passages 8, whilelodged in the closed end of the receptacle or chamber 5 is a mass 9 ofsuitable fumigating material, of'which formaldehyde may constitute theactive fumigating agent; It is to be preferred that the mass 9 be solidat ordinary temperatures, so that the device may be transported fromplace to place without danger of spilling the disinfectant compound, butsuch compound will readily liquefy and vaporize under the heat due tothe action of a candle 3.

Adapted to the open end of the member or compartment 5 there is acup-like member 10, generally similar to the member 5, which is alsocup-like in shape, and like the members 5 and 1, the member 10 may becylindrical. The member 10 is closed at one end and is there contractedin diameter, as indicated at 11, so as to enter for a distance into theopen end of the member 5, and where the contracted portion and the mainportion of the member 10 join, there are formed shoulders 12 adapted torest on the Patented Mal-.26, 1912.

walls of the member 5 at the open end thereof. The member 10, however,is in its body portion of greater internal diameter than-the member 5,so that the member 5 will enter the open end of the member 10 up to thecontracted portion 11 and the larger portion of the member 10 is ofsuflicient length to wholly close the openings 8 when in position to actas a cap for the member 5, the last named position of the parts beingillustrated in Fig. 2, where it will be seen that the openings 8 are allclosed by the walls of the member 5 and that the open end of the member5 is closed by the contracted end 11 of the member 10, wherefore anygases escaping from the compound 9 will have no means of exit from theinterior of the member 5, so long as the member 10 is in inclosingrelation thereto.

When the parts are in position for operation, the member 1 is placedupon some means of support in an approximately horizontal position, sothat the member 1 stands about upright with the member 5 resting on theupper end of the member 1 and the contracted end thereof nesting in theopen end of the member 1, while the member 10 is placed upon the openend of the member 5, so as to close the same by the entrance of thecontracted end 11 into nesting rela tion with the open end of the member5, and then Water indicated at 9 in Fig. 1 may be placed within themember 10, after which the wick l is lighted and the flame thereof willserve to heat the mass 9, driving off in the form: of gas or vapor theformaldehyde or other such disinfectant which will escape through theopenings 8 and being then in a heated condition will rise around theouter Walls of the member 10. As the apparatus continues in opera tion,the heat developed is suflicient to vaporize the water 9 and this willescape through the open end of the cup, like member 10 in the form ofvapor or steam, mingling with the rising gases of disinfectant escapingthrough the openings 8, so that there is produced a steam like masscontaining an appropriate amount of disinfectant and this mass beingconsiderably heated will rise and spread through a room conveying thedisinfectant to all parts of the room, and because of the moist natureof the mixture, it is in the best condition for action as a germicide.Air for the flame of the burning wick 4 finds its way through theopenings 2 and the products of combustion also find their way from theinterior of the member 1 to the outer air throughthe openings 2 tomingle with and heat the disinfectant passing through the openings 8 andthe watery vapor rising from the open end of the member 10.

When the device is assembled as in Fig. 2 for shipment or storage, it iscustomary to seal the edges of the member 10 where inclosing the member5 with wax or some such preparation, which will more effectively preventthe escape of any of the formaldehyde vapor or gas, and whileformaldehyde has been mentioned as the preferred form of disinfectant orgermicide, it may be stated that any other suitable disinfectant may beemployed. In practical operation the formula to be used should consistof tallow, glycerin and paraformaldehyde, the percentage of theingredients being determined by the space to be disinfected.

The bottom of the whole burner has a small space 13 under the fire tocontain water, which may be introduced through a lip 14, so that thewater will be underneath the burner to prevent the apparatus frombecoming hot and burning anything it is placed upon.

What is claimed is 1. An apparatus for fumigating, comprising a heatingchamber, a chamber for the reception of a disinfectant provided withoutlets for the discharge of vapor or gas and adapted to rest on and besupported by the heating chamber, and a chamber for the reception ofwater adapted to rest on and be supported by the chamber for thedisinfectant, the water chamber being of a size to serve as a cover andclosure for the disinfectant chamber and its outlets when inverted andapplied thereto.
